SECTION 2.5Thermal Effects163Problem 2.5-15Pipe 2 has been inserted snugly into Pipe 1, but the holes for a connecting pin do not line up: there is a gap s.The user decides to apply eitherforce P1to Pipe 1 orforce P2toPipe 2, whichever is smaller. Determine the following using thenumerical properties in the box.(a)If only P1is applied, find P1(kips) required to close gap s;if a pin is then inserted and P1removed, what are reactionforces RAand RBfor this load case?(b)If only P2is applied, find P2(kips) required to close gap s;if a pin is inserted and P2removed, what are reactionforces RAand RBfor this load case?(c)What is the maximum shearstress in the pipes, for theloads in (a) and (b)?(d)If a temperature increase Tis to be applied to the entirestructure to close gap s(instead of applying forces P1andP2), find the Trequired to close the gap. If a pin is insertedafter the gap has closed, what are reaction forces RAand RBfor this case?
